Ok, here's a question - What do you notice about this aeroplane? For a start it has no markings, no registration, and no identifying marks at all. It came up behind us while we were still about 1000 miles to run to Muscat. We were at 27,000 feet, and he flew right over us and turned away as he passed in front of us. Nothing was said by the controller, and I didn't hear anything on the radio, so it's all a bit of a mystery. If he'd been a few feet lower, he would have set off our traffic awareness system and probably given us a bit of a fright. Even though I knew he was there, I had no idea what he was up to.
Since we were where we where, I thought it best not to ask any questions..... still wondering though.
